Abstract (en)
[origin: US4935594A] A method for manufacturing an eroding electrode which has an outer layer consisting of a structural composition having a resistance against erosive wear characteristic many times greater than the common eroding electrode. The outer layer initially consists of one or several coatings of a metal alloy having a low volatilization temperature encasing a core of metal or a metal alloy. The encased wire electrode is then annealed at such temperatures until an alloy, which extends from the outer surface of the encasement toward the core, is created and which has a decreasing content of the consitutents of the low volatilzation temperature material or alloy, after which the wire electrode is cooled in a controlled manner to fix the diffusion states.
